It's actually a fairly rational fear in this case. – Always incendiary. Projectiles explode multiple times mid-flight at set time intervals before impact.
Usage & Description
Due to the nature of the projectile, the Pyrophobia is best used in closed areas or catwalks with several enemies in a line. Shooting just over or to the side of enemies will allow it to score hits on multiple enemies. Since the secondary explosions are based on time, not distance, skills that increase projectile speed, such as Maya's Accelerate or Zer0's Vel0city will decrease the effectiveness of this weapon by causing it to have fewer explosions over the same distance.
The Maliwan-type scope and exhaust will diminish the utility of this launcher's special effect, as they increase missile speed.
The Torgue exhaust will decrease the projectile's velocity and allow more explosions to appear.
The novas cause self-damage. This mostly happens when firing the weapon while walking forward, and only when the rocket is slow enough.
Pyrophobia is the irrational fear of fire or flame.
The Pyrophobia is very similar to a legendary rocket launcher made by Maliwan in Borderlands, the Rhino.
